Fme24x not heating and burning smell with loud noise

If that grinding noise sounds a little like gargling into a coffee cup, that's a defective magnetron.

Is there any holes burnt into the liner inside the micro wave.? Or burn spots showing.? If there is thow it out. It is not safe to be useing it.It could start on fire. That problem is from when they are not clean out once in a while. End food is burn,t onto the interior liner end grease end oil,

The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

Loud hum is usually due to faulty hv diod, resonance capacitor, or the magnatrone feed thru capacitor , chk it with a ohm meter , one by one n replace it .. zaheer Islamabad

If you can remove it look for burnt areas which may can be scraped off or you may need to replace it. An appliance parts store usually has the material you can cut to fit you own.

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

Chances are you have a bad magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

yes anything can be fixed but a do it yourselfer i reccomend against this cause thats a radiated element in the micro
recommend go out and purchase a replacement go with G.E. they have the 7 year warranty great little micro. too change out is easy

The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!
